14 Claims.

This invention relates to heel making and is disclosed as embodied in a machine for turning wood heels.

Wood heels are generally covered with a sheet of flexible material, such as leather, cloth, or pyroxylin, wrapped around the heel with the edges of the cover in front. A neat appearance may be secured by tucking the edges of the cover into a vertical slot in the heel breast, as explained in United States Letters Patents No. 1,718,177, granted June 18, 1929, and No. 1,751,359, granted June 3, 193-0, on applications of William H. Nutt. The former of these patents discloses a heel having a single slot in its breast and the latter a heel having three parallel slots in its breast, forming two thin tongues which yield laterally when the cover is tucked into the central slot.

These slots are preferably formed during the breast grooving operation, whi h is the first operation in heel making after the severance of the rough blank: the turning, which forms the back and side surfaces of the heel, is one later.

t is therefore necessary to gauge the grooved and slotted heel blank accurately in the turning machine in order that the side surfaces be formed in the correct relation to the already formed slot or slots.

The turning operation is performed in a machine substantially as shown in United States Letters Patent No. 1,488,534, granted April 1, i924, cn-the application of Folsom, Vinton and W .itney. In this machine the heel blank is held between two gripping jaws engaging its top-lift and attaching surfaces, and is gauged by a contact at the breast and at the side, the latter gauge being shown in United States Letters Patent No. 1,715,660, granted June 4, 1929, on the application of Ralph 35. Knight.

It is an important object of this invention to provide an improved mechanism adapted for use in machines of the type referred to for gauging heel blanks provided with the slots above described, which shall make use of the slots themselves in gaugin Preferably also the improved gauge mechanism will be organized to deal with either type of slotted heel blank discussed above, and also with the plain, unslotted heel blank.

Accordingly, I have provided a breast gauging mechanism adapted to engage a slot or slots in slotted heel blanks, in which, in the embodiment of the invention herein illustrated, a toothed instrumentality is provided with a plurality of toothed portions adapted to engage one or more slots respectively in a slotted heel blank. Preferably the toothed instrumentality is mounted on a breast gauge, in such manner that its toothed portions can be rendered inoperative, thus converting it into a breast gauge of general utility. In the preferred embodiment of the invention, the toothed member is formed as a plate having one tooth on one end and two on the other, clamped to and pivotaily adjustable on the main body of the breast gauge, the pivotal adjustment permit mg one, two, or no teeth to be put into operative position.

In accordance with another feature of the inention, referring to the machine organization if, it is cont inplated that the gauge as a wh le may be pivotally adjustable to compensate to degree for adventitious faulty adjustment of the machine itself and for uneven wear on the two sides of the machine.

These and other featu es of the invention conipric 1g certain combinations and arrangements of pars will be apparent from the following de l scription of a preferred embodiment of the invention shown in the drawing, in which Fig. l is a side eievation of a part of the wood heel turning machine;

Fig. 2 is a plan view of the gauge with a triply slotted heel blank;

3 is a View of the gauge in contact with a singly slotted heel blank; and

a perspective view of the gauge.

gen l descriptors of the machine 53 ll be found in the Folsom,

Whitney patent acve referred to.

niprises two cutters 10 on vertical in contact fl? s means the jack can be swung over toward the cutter 10 to bring the heel blank 22 in contact with the cutter, and then turned to trim the blank from a breast edge to the back. The depth of cut is controlled by a form 24 running against a guard 26, as the jack is turned to swing the heel blank past the cutter.

The lower jack jaw 28 has a rib formed on its 160 left end (Fig. l) which fits a groove 30 in the bottom of a breast gauge carrying block 32. The block 32 is slotted at 3% to permit adjustment, and is clamped in position by a screw 36 in the slot.

block 32 is also horizontally slotted at 38 it; to receive a gauge plate so which is held in posit'on by a small screw 42 passing through the block plate. screw is not set up so tight as to prevent turning of the plate in the block. The left end of the plate (Fig. 2) is slotted at 44, the

shaft 2c.

width of the slot being greater than the diameter of the screw 36. Thus the plate 40 can be swung on the screw 42 when the screw 36 is loosened, but is immovably clamped in the slot 38 when the screw 36 is tight, the upper face of the block 32 yielding under the screw tens on. The right end 46 of the plate 40 is more flatly curved than any heel breast ordinarily met with, so that it will contact with a heel blank 22 at two separated points, as shown in Figs. 2 and 3, thus positively gauging the orientation of the heel blank. The gauge, as so far described, will gauge the ordinary, unslotted heel blank, in the ordinary manner.

A toothed member 48, having, in the form illustrated, one tooth 49 on one end and two on the other, is pivotally mounted and clamped on the plate to by a screw 50. It cabe set with the teeth at either end projecting slightly beyond the end 46 of the plate 40, as in Figs. 2 and 3, or with all teeth out of operative position, as in Fig. 4. The teeth, when in operative position, engage the slot of a single slotted heel blank (Fig. 3) or two of the slots of a triply slotted blank (Fig. 2), and gauge the blank, definitely and with minimum eiiort, in properly centered position. When arranged as in Fig. 4 the gauge is suitable for use on an unslotted heel blank. Preferabiy the heel blank is gauged also by the plate 40 when the teeth 49 are used, the teeth centering the lank on the plate 40.

One purpose or the pivotal adjustment of the plate 40 at 42 is to correct minor inaccuracies in the form 24. The form 24 is made of wood and is shaped to the particular style of heel being cut, by filing. Uneven wear or faulty filing tend to result in slightly unsymmetrical heels and such a ditliculty can be corrected to a degree by throwing the plate 40 oh center a. little, thus centering the heel blank be ter relativelv to the form 24 itself.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. A gauge for a. wood heel cutting machine comprising a toothed member having a plurality of sets of toothed portions, adjustable to bring a selected toothed portion into operative position to engage a. corresponding set of slots in a heel blank.

2. A gauge for a wood heel cutting machine comprising a breast gauging plate, and a toothed member mounted thereon, said toothed member being movable to position a tooth beyond the gauging edge of the plate, or to lie entirely within the gauging edge of the plate, as desired.

3. A gauge for a wood heel cutting machine comprising a breast gauge having a gauging edge of flatter curvature than horizontal cross-section of a heel breast, and a toothed member mounted thereon with a tooth projecting over the gauging edge, to cooperate with a slot in the breast of a heel blank.

4. A gauge for a wood heel cutting machine comprising a breast gauge having a gauging edge of flatter curvature than horizontal cross-section of a heel breast, and a toothed member mounted thereon with a tooth projecting over the gauging edge, to cooperate with a slot in the breast of a heel blank, the tooth being also retractible from operative position to permit gauging an unslotted heel blank.

5. A gauge for a wood heel cutting machine comprising a gauge carrying block, a gauge plate pivotally adjustable thereon, and a toothed member mounted on the plate with a tooth projecting past the edge thereof, to cooperate with a slot in the breast of a heel blank.

6. A gauge for a wood heel cutting machine comprising a gauge carrying block having two intersecting slots therein, a gauge plate pivotally mounted in one said slot and having a slot in line with the other slot in the gauge carrying block, said slot in the plate being wider than said other slot in the block, to permit adjustment of the plate in the slot in which it is mounted without interference with a screw in said other slot in the block.

7. A gauging member for a wood heel making machine comprising a supporting member, and a member having a plurality of groups of teeth with a different number of teeth in each group, said member being adjusted to bring a desired group into gauging position.
